Performance Monitoring
Note The terms “Unidirectional Path Switched Ring” and “UPSR” may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as “Path Protected Mesh Network” and “PPMN,” refer generally to Cisco’s path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.

Performance monitoring (PM) parameters are used by service providers to gather, store, set thresholds, and report performance data for early detection of problems. In this chapter, PM parameters and concepts are defined for electrical cards, Ethernet cards, and optical cards in the Cisco ONS 15454 SDH.

For information about enabling and viewing PM values, refer to the Cisco ONS 15454 SDH Procedure Guide.

Chapter 4 Performance Monitoring4.1 Threshold Performance Monitoring

4.1 Threshold Performance MonitoringThresholds are used to set error levels for each PM parameter. You can set individual PM threshold values from the Cisco Transport Controller (CTC) card view Provisioning tab. For procedures on provisioning card thresholds, such as line, path, and SDH thresholds, refer to the Cisco ONS 15454 SDH Procedure Guide.

During the accumulation cycle, if the current value of a performance monitoring parameter reaches or exceeds its corresponding threshold value, a threshold crossing alert (TCA) is generated by the node and displayed by CTC. TCAs provide early detection of performance degradation. When a threshold is crossed, the node continues to count the errors during a given accumulation period. If 0 is entered as the threshold value, the performance monitoring parameter is disabled.

Note Due to limitation of memory and number of TCAs generates by different platforms, you can manually add/modify the following two (2) properties to their property file (CTC.INI for Windows and .ctcrc for Unix) to fit the need:ctc.15xxx.node.tr.lowater=yyy (where xxx is platform and yyy is number of lowater mark. Default lowater makr is 25)ctc.15xxx.node.tr.hiwater=yyy (where xxx is platform and yyy is number of hiwater mark. Default hiwater mark is 50)If the number of incoming TCA is greater than the hiwater, it will keep the latest lowater and discard older ones.

Change the threshold if the default value does not satisfy your error monitoring needs. For example, customers with a critical E1 installed for 911 calls must guarantee the best quality of service on the line; therefore, they lower all thresholds so that the slightest error raises a TCA.

4.2 Intermediate-Path Performance MonitoringIntermediate-path performance monitoring (IPPM) allows transparent monitoring of a constituent channel of an incoming transmission signal by a node that does not terminate that channel. Many large ONS 15454 SDH networks only use line terminating equipment (LTE), not path terminating equipment (PTE). Table 4-1 shows ONS 15454 SDH cards that are considered LTE.

Chapter 4 Performance Monitoring4.3 Pointer Justification Count Performance Monitoring

Software Release 3.0 (R3.0) and later allow LTE cards to monitor near-end PM data on individual high-order paths by enabling IPPM. After enabling IPPM provisioning on the line card, service providers can monitor high-order paths that are configured in pass-through mode on an ONS 15454 SDH operating in SDH AU4 mode, thus making troubleshooting and maintenance activities more efficient.

IPPM occurs only on high-order paths that have IPPM enabled, and TCAs are raised only for PM parameters on the IPPM enabled paths. The monitored IPPM parameters are HP-EB, HP-BBE, HP-ES, HP-SES, HP-UAS, HP-ESR, HP-SESR, and HP-BBER.

Note The E1 card and STM-1 card can monitor far-end IPPM. For all other cards listed in Table 4-1, far-end IPPM is not supported. However, SDH path PM parameters can be monitored by logging into the far-end node directly.

The ONS 15454 SDH performs IPPM by examining the overhead in the monitored path and by reading all of the near-end path PM values in the incoming direction of transmission. The IPPM process allows the path signal to pass bidirectionally through the node completely unaltered.

For detailed information about specific IPPM parameters, locate the card name in the following sections and review the appropriate definition.

4.3 Pointer Justification Count Performance MonitoringPointers are used to compensate for frequency and phase variations. Pointer justification counts indicate timing errors on SDH networks. When a network is out of synchronization, jitter and wander occur on the transported signal. Excessive wander can cause terminating equipment to slip.

Slips cause different effects in service. Voice service has intermittent audible clicks. Compressed voice technology has short transmission errors or dropped calls. Fax machines lose scanned lines or experience dropped calls. Digital video transmission has distorted pictures or frozen frames. Encryption service loses the encryption key causing data to be transmitted again.

Pointers provide a way to align the phase variations in VC4 payloads. The VC4 payload pointer is located in the H1 and H2 bytes of the AU pointers section and is a count of the number of bytes the VC4 path overhead (POH) J1 byte is away from the H3 byte, not including the section overhead bytes. Clocking differences are measured by the offset in bytes from the pointer to the first byte of the VC4 POH called the J1 byte. Clocking differences that exceed the normal range of 0 to 782 can cause data loss.

There are positive (PPJC) and negative (NPJC) pointer justification count parameters. PPJC is a count of path-detected (PPJC-Pdet) or path-generated (PPJC-Pgen) positive pointer justifications. NPJC is a count of path-detected (NPJC-Pdet) or path-generated (NPJC-Pgen) negative pointer justifications depending on the specific PM name.

A consistent pointer justification count indicates clock synchronization problems between nodes. A difference between the counts means the node transmitting the original pointer justification has timing variations with the node detecting and transmitting this count. Positive pointer adjustments occur when the frame rate of the POH is too slow in relation to the rate of the VC4.

Chapter 4 Performance Monitoring4.6 Performance Monitoring for Ethernet Cards

4.6 Performance Monitoring for Ethernet CardsThe following sections define performance monitoring parameters and definitions for the E-Series, G-Series, and ML-Series Ethernet cards.

4.6.1 E-Series Ethernet Card Performance Monitoring ParametersCTC provides Ethernet performance information, including line-level parameters, port bandwidth consumption, and historical Ethernet statistics. The E-Series Ethernet performance information is divided into the Statistics, Utilization, and History tabbed windows within the card view Performance tab window. The following sections describe PM parameters provided for the E100T-G and E1000-2 Ethernet cards.

4.6.1.1 E-Series Ethernet Statistics Window

The Ethernet statistics window lists Ethernet parameters at the line level. The Statistics window provides buttons to change the statistical values shown. The Baseline button resets the displayed statistics values to zero. The Refresh button manually refreshes statistics. Auto-Refresh sets a time interval at which automatic refresh occurs.

Table 4-6 defines the E-Series Ethernet card Statistics parameters.

Table 4-6 E-Series Ethernet Statistics Parameters

Parameter Meaning

Link Status Link integrity indicator (up means present, and down means not present).

Rx Packets Number of packets received since the last counter reset.

Rx Bytes Number of bytes received since the last counter reset.

Tx Packets Number of packets transmitted since the last counter reset.

Tx Bytes Number of bytes transmitted since the last counter reset.

Rx Total Errors Total number of receive errors.

Rx FCS Number of packets with a Frame Check Sequence (FCS) error. FCS errors indicate frame corruption during transmission.

Rx Alignment Number of packets with alignment errors (received incomplete frames).

Rx Runts Measures undersized packets with bad cyclic redundancy check (CRC) errors.

Rx Shorts Measures undersized packets with good cyclic redundancy check (CRC) errors.

Rx Oversized + Jabbers Measures oversized packets and jabbers. Size is greater than 1522 errors regardless of cyclic redundancy check (CRC) errors.

Rx Giants Number of packets received that are greater than 1518 bytes in length for untagged interfaces and 1522 bytes for tagged interfaces.


December 2004

Chapter 4 Performance Monitoring4.6.1 E-Series Ethernet Card Performance Monitoring Parameters

4.6.1.2 E-Series Ethernet Utilization Window

The Utilization window shows the percentage of transmit (Tx) and receive (Rx) line bandwidth used by the Ethernet ports during consecutive time segments. The Mode field displays the real-time mode status, such as “100 Full,” which is the mode setting configured on the E-Series port. However, if the E-Series port is set to autonegotiate the mode (Auto), this field shows the result of the link negotiation between the E-Series and the peer Ethernet device attached directly to the E-Series port.

The Utilization window provides an Interval menu that enables you to set time intervals of 1 minute, 15 minutes, 1 hour, and 1 day. Line utilization is calculated with the following formulas:

Rx = (inOctets + inPkts * 20) * 8 / 100% interval * maxBaseRate

Tx = (outOctets + outPkts * 20) * 8 / 100% interval * maxBaseRate

The interval is defined in seconds. The maxBaseRate is defined by raw bits per second in one direction for the Ethernet port (that is, 1 Gbps). STS circuit maxBaseRates are shown in Table 4-7.

Note Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.

Note The E-Series Ethernet card is a Layer 2 device or switch and supports Trunk Utilization statistics. The Trunk Utilization statistics are similar to the Line Utilization statistics, but shows the percentage of circuit bandwidth used rather than the percentage of line bandwidth used. The Trunk Utilization statistics are accessed via the card view Maintenance tab.

Tx Collisions Number of transmit packets that are collisions; the port and the attached device transmitting at the same time caused collisions.

Tx Late Collisions Number of frames that were not transmitted since they encountered a collision outside of the normal collision window. Normally, late collision events should occur only rarely, if at all.

Tx Excessive Collisions Number of consecutive collisions.

Tx Deferred Number of packets deferred.

4.6.1.3 E-Series Ethernet History Window

The Ethernet History window lists past Ethernet statistics for the previous time intervals. Depending on the selected time interval, the History window displays the statistics for each port for the number of previous time intervals as shown in Table 4-8. The listed parameters are defined in Table 4-6 on page 4-19.

4.6.2 G-Series Ethernet Card Performance Monitoring ParametersCTC provides Ethernet performance information, including line-level parameters, port bandwidth consumption, and historical Ethernet statistics. The G-Series Ethernet performance information is divided into the Statistics, Utilization, and History tabbed windows within the card view Performance tab window. The following sections describe PM parameters provided for the G1000-4 and G1K-4 Ethernet cards.

4.6.2.1 G-Series Ethernet Statistics Window

The Ethernet statistics window lists Ethernet parameters at the line level. The Statistics window provides buttons to change the statistical values shown. The Baseline button resets the displayed statistics values to zero. The Refresh button manually refreshes statistics. Auto-Refresh sets a time interval at which automatic refresh occurs. The G-Series Statistics window also has a Clear button. The Clear button sets the values on the card to zero, but does not reset the G-Series card.

Table 4-9 defines the G-Series Ethernet card Statistics parameters.

Parameter Meaning

Time Last Cleared A time stamp indicating the last time statistics were reset.

Link Status Indicates whether the Ethernet link is receiving a valid Ethernet signal (carrier) from the attached Ethernet device; up means present, and down means not present.







December 2004


Note Do not use the High-Level Data Link Control (HDLC) errors counter to count the number of frames dropped because of HDLC errors, because each frame can fragment into several smaller frames during HDLC error conditions and spurious HDLC frames can also be generated. If HDLC error counters are incrementing when no SDH path problems should be present, it might indicate a problem with the quality of the SDH path. For example, a SDH protection switch generates a set of HLDC errors. But the actual values of these counters are less significant than the fact they are changing.

Rx FCS Number of packets with a Frame Check Sequence (FCS) error. FCS errors indicate frame corruption during transmission.

Rx Alignment Number of packets with received incomplete frames.

Rx Runts Measures undersized packets with bad cyclic redundancy check (CRC) errors.

Rx Shorts Measures undersized packets with good CRC errors.

Rx Jabbers Total number of frames received that exceed the 1548-byte maximum and contain CRC errors.

Rx Giants Number of packets received that are greater than 1530 bytes in length.

Rx Pause Frames Number of received Ethernet IEEE 802.3z pause frames.

Tx Pause Frames Number of transmitted IEEE 802.3z pause frames.

Rx Pkts Dropped Internal Congestion

Number of received packets dropped due to overflow in G-Series frame buffer.

Tx Pkts Dropped Internal Congestion

Number of transmit queue drops due to drops in the G-Series frame buffer.

HDLC Errors High-level data link control (HDLC) errors received from SDH/SONET (see note).

Rx Unicast Packets Number of unicast packets received since the last counter reset.

Tx Unicast Packets Number of unicast packets transmitted.

Rx Multicast Packets Number of multicast packets received since the last counter reset.

Tx Multicast Packets Number of multicast packets transmitted.

Rx Broadcast Packets Number of broadcast packets received since the last counter reset.

Tx Broadcast Packets Number or broadcast packets transmitted.

4.6.2.2 G-Series Ethernet Utilization Window

The Utilization window shows the percentage of transmit (Tx) and receive (Rx) line bandwidth used by the Ethernet ports during consecutive time segments. The Mode field displays the real-time mode status, such as “100 Full,” which is the mode setting configured on the G-Series port. However, if the G-Series port is set to autonegotiate the mode (Auto), this field shows the result of the link negotiation between the G-Series and the peer Ethernet device attached directly to the G-Series port.

The Utilization window provides an Interval menu that enables you to set time intervals of 1 minute, 15 \minutes, 1 hour, and 1 day. Line utilization is calculated with the following formulas:



The interval is defined in seconds. The maxBaseRate is defined by raw bits per second in one direction for the Ethernet port (that is, 1 Gbps). The maxBaseRate for G-series STS is shown in Table 4-10.


Note Unlike the E-Series, the G Series card does not have a display of Trunk Utilization statistics, because the G-Series card is not a Layer 2 device.

4.6.2.3 G-Series Ethernet History Window

The Ethernet History window lists past Ethernet statistics for the previous time intervals. Depending on the selected time interval, the History window displays the statistics for each port for the number of previous time intervals as shown in Table 4-11. The listed parameters are defined in Table 4-9 on page 4-21.

The ML-Series Ethernet performance information is divided into the Ether Ports and Packet over SONET/SDH (POS) Ports tabbed windows within the card view Performance tab window. The following sections describe PM parameters provided for the ML100T-12 and ML1000-2 Ethernet cards.

4.6.3.1 ML-Series Ether Ports Window

The Ether Ports window lists Ethernet PM parameter values for each Ethernet port on the card. Auto-Refresh sets a time interval at which automatic refresh will occur. The PM values are a snapshot captured at the time intervals selected in the Auto-Refresh field. Historical PM values are not stored or displayed.

Chapter 4 Performance Monitoring4.7 Performance Monitoring for Optical Cards

4.7 Performance Monitoring for Optical CardsThe following sections define performance monitoring parameters and definitions for the STM-1, STM1 SH 1310-8, STM-1E, STM-4, STM4 SH 1310-4, STM16 SH AS 1310, STM16 LH AS 1550, STM16 EH 100 GHz, STM64 IO 1310, STM64 SH 1550, STM64 LH 1550, and STM64 LH ITU 15xx.xx, cards.

On all STM-N optical cards errors are calculated in bits instead of blocks for B1 and B3. This means there could possibly be a slight difference between what is inserted and what is reported on CTC. In STM4 for example, there are approximately 15,000 to 30,000 bits per block (per ITU-T-G.826). If there were two bit errors within that block, the standard would require reporting one block error whereas the STM-N cards would have reported two bit errors.

When a tester inputs only single errors during testing, this issue would not appear because a tester is not fast enough to induce two errors within a single block. However, if the test is performed with an error rate, certain error rates could cause two or more errors in a block. For example, the STM4 is roughly 622 Mbps and the block in the STM4 has 15,000 bits, there would be about 41,467 blocks in a second. If the tester inputs a 10e-4 error rate, that would create 62,200 errors per second. If the errors are distributed uniformly, then CTC could potentially report two bit errors within a single block. On the other hand, if the error ratio is 10e-5, then there will be 6,220 errors per second. If the errors are not distributed uniformly, then CTC might report one bit error within a single block. In summary, if the errors are distributed equally, then a discrepancy might be seen with the standard when a tester inputs 10e-4 or 10e-3 error rates.

Chapter 4 Performance Monitoring4.9 Performance Monitoring for the Fiber Channel Card

4.9 Performance Monitoring for the Fiber Channel CardThe following sections define performance monitoring parameters and definitions for the FC_MR-4 card.

4.9.1 FC_MR-4 Card Performance Monitoring ParametersCTC provides FC_MR-4 performance information, including line-level parameters, port bandwidth consumption, and historical statistics. The FC_MR-4 card performance information is divided into the Statistics, Utilization, and History tabbed windows within the card view Performance tab window.

4.9.1.1 FC_MR-4 Statistics Window

The Statistics window lists parameters at the line level. The Statistics window provides buttons to change the statistical values shown. The Baseline button resets the displayed statistics values to zero. The Refresh button manually refreshes statistics. Auto-Refresh sets a time interval at which automatic refresh occurs. The Statistics window also has a Clear button. The Clear button sets the values on the card to zero. All counters on the card are cleared.

Table 4-23 defines the FC_MR-4 card Statistics parameters.

Parameter Meaning

Time Last Cleared A time stamp indicating the last time statistics were reset.

Link Status Indicates whether the fibre channel link is receiving a valid fibre channel signal (carrier) from the attached fibre channel device; up means present, and down means not present.

Rx Frames A count of the number of fiber channel frames received without errors.

Rx Bytes A count of the number of bytes received without error for the fiber channel payload.

Tx Frames A count of the number of transmitted fiber channel frames.

Tx Bytes A count of the number of bytes transmitted from the fiber channel frame.

8b/10b Errors A count of 10b errors received by the serial/deserializer (serdes 8b/10b).

Encoding Disparity Errors A count of the disparity errors received by serdes.

Link Recoveries A count of the FC-MR software initiated link recovery attempts toward the FC line side because of SONET protection switches.

Rx Frames bad CRC A count of the received fiber channel frames with errored CRCs.

Tx Frames bad CRC A count of the transmitted fiber channel frames with errored CRCs.

Rx Undersized Frames A count of the received fiber channel frames < 36 bytes including CRC, start of frame (SOF), and end of frame (EOF).

Rx Oversized Frames A count of the received fiber channel frames > 2116 bytes of the payload. Four bytes are allowed for supporting VSAN tags sent.

GFP Rx HDR Single-bit Errors A count of generic framing procedure (GFP) single bit errors in the core header error check (CHEC).

GFP Rx HDR Multi-bit Errors A count of GFP multibit errors in CHEC.

GGFP Rx Frames Invalid Type A count of GFP invalid user payload identifier (UPI) field in the type field.
